Buddy list-based sharing of electronic content

ABSTRACT

Instant messaging (IM) entities may be invited to an electronic calendar event using an instant message. Selecting the IM entities as invitees to the event may include dragging and dropping names of the IM entities from a buddy list of an IM application to an event from an electronic calendar application, or vice versa. A method of inviting an entity to a calendar event includes providing a calendar event from a calendar application and recognizing, by the calendar application, an IM entity as an invitee to the event.

TECHNICAL FIELD

This document relates to sharing electronic content with an entity usingelectronic messages.

BACKGROUND

Scheduling an electronic calendar event may involve proposing a specificdate and time to one or more potential event participants (i.e.,inviting), and modifying the date and time of the event based on theavailability of those participants. The participants typicallycommunicate to determine a time when they are available to attend theevent. Electronic mail (“e-mail”) may be the communication medium usedto schedule such an event.

SUMMARY

In one general aspect, a method for sharing electronic content includesenabling access to a buddy list user interface that makes perceivableuser-identified online identities and real time presence information forat least some of those online identities. Based on user manipulation ofthe buddy list user interface, designation of several online identitiesthat constitute a subset of the online identities for whom presence isindicated within the buddy list is enabled. An indication of content tobe shared with each of the online identities designated is received fromthe user. Separate communications are established with each of theonline identities designated by the user. Content is communicated onbehalf of the user independently to each of the online identitiesdesignated by the user.

In another general aspect, a computer system for sharing electroniccontent includes an access module configured to enable access to a buddylist user interface that makes perceivable user-identified onlineidentities and real time presence information for at least some of thoseonline identities. The computer system also includes a user designationmodule configured to enable designation of several online identitiesthat constitute a subset of the online identities for whom presence isindicated within the buddy list based on user manipulation of the buddylist user interface and a content selection module configured to receivefrom the user an indication of content to be shared with each of thedesignated online identities. The computer system also includes acommunications establishing module configured to establish separatecommunications with each of the online identities designated by the userand a communications module configured to communicate content on behalfof the user independently to each of the online identities designated bythe user.

In another general aspect, an apparatus for sharing electronic contentincludes access means for enabling access to a buddy list user interfacethat makes perceivable user-identified online identities real timepresence information for at least some of those online identities. Theapparatus also includes user designation means for enabling designationof several online identities that constitute a subset of the onlineidentities for whom presence is indicated within the buddy list, basedon user manipulation of the buddy list interface, and content selectionmeans receiving from the user an indication of content to be shared witheach of the designated online identities. The apparatus also includescommunications establishing means for establishing separatecommunications with each of the online identities designated by the userand communications means for communicating content on behalf of the userindependently to each of the online identities designated by the user.

Implementations may include one or more of the following features. Forexample, communicating independently may include establishing a separateinstant messaging session between the user and each of the onlineparticipants. Responses received from each online participant may not beviewable by the other online participants. The content specified by theuser may be made available to each of the designated onlineparticipants.

Designating may include selecting particular online identities using amouse pointer. Designation of several online identities may be a manualprocess performed by a user. The manual process may involve manualselection of each online identity individually, using a pointing device.

The content to be shared may be a calendar event. The calendar event maybe dropped onto a representation of the designated online identities inthe buddy list to inspire communication of the calendar event, or acorresponding invitation, to each of the designated online identifiesseparately. A representation of the designated online identities in thebuddy list may be dropped onto the calendar event to inspirecommunication of the calendar event, or a corresponding invitation, toeach of the designated online identifies separately.

The content to be shared may be dropped onto a representation of thedesignated online identities in the buddy list to inspire communicationof the content to each of the designated online identities separately.

A representation of the designated online identities in the buddy listmay be dropped onto the content to be shared to inspire communication ofthe content to each of the designated online identities separately.

Communicating the content to each of the online identities designated bythe user may include determining which of the designated onlineidentities are presently online. The content may be communicated to thedesignated online identities that are presently online using instantmessaging, and the content may be communicated to the designated onlineidentities that are not presently online using a communications programother than instant messaging. Electronic mail may be the communicationsprogram used to communicate the content to the designated onlineidentities that are not presently online. Instant messages may be usedto communicate the content, wherein delivery of the instant messages isdelayed until the designated online identities that are not presentlyonline to the designated online identities that are not presently onlineare again online. The user may be provided with options to communicatethe content to the designated online identities that are not presentlyonline using a communications program other than instant messaging.

Communicating the content to each of the designated online identitiesmay include resolving a cascaded delivery rule for each of thedesignated online identities to choose a delivery mechanism forcommunicating the content to each of the designated online identitiesand using each of the chosen delivery mechanisms to communicate thecontent to the corresponding designated online identity. A delivery rulemay be specified for each of the designated online identities by each ofthe designated online identities. The user may specify a delivery rulefor each of the designated online identities.

Receiving the indication of the content to be shared with each of thedesignated online identities may occur before designation of the onlineidentities. Receiving the indication of the content to be shared witheach of the designated online identities may occur after designation ofthe online identities.

In another general aspect, a method of sharing electronic contentincludes enabling user generation of application-specific, sharableelectronic content. User selection of a first instant messaging entityand a second instant messaging entity is received. A single message thatincludes the application-specific, shareable electronic content and thatis to be associated with the first instant messaging entity and thesecond instant messaging entity is generated. The user is enabled tosend the message using an instant messaging platform that is sentconcurrently to the first instant messaging entity and the secondinstant messaging entity. Responses received from the first and thesecond instant messaging entities are mediated.

Implementations may include one or more of the following features. Forexample, the electronic content may be a calendar event from a calendarapplication, and recognizing the first instant messaging entity and thesecond instant messaging entity may include recognizing the firstinstant messaging entity and the second instant messaging entity asinvitees to the calendar event.

An invitation to the calendar event for the first instant messagingentity may be generated by the calendar application. The message may bean invitation to the calendar event. Enabling the user to send themessage may include enabling the user to send the invitation from thecalendar application to an instant messaging server. Enabling the userto send the message may include enabling the user to send the invitationto a communications application and allowing the communicationsapplication to deliver the invitation to the first instant messagingentity and the second instant messaging entity. The communicationsapplication may be an instant messaging application.

The first instant messaging entity and the second instant messagingentity to the calendar event using instant messages may be automaticallyinvited in response to recognizing the first instant messaging entityand the second instant messaging entity as invitees. Automaticallyinviting may include sending an invitation to the calendar event to thefirst instant messaging entity and the second instant messaging entityusing instant messages.

Recognizing the first instant messaging entity and the second instantmessaging entity as invitees may be performed in response to a userdragging the calendar event from the calendar application to arepresentation of the first instant messaging entity and arepresentation of the second instant messaging entity. Recognizing thefirst instant messaging entity and the second instant messaging entityas invitees may be performed in response to a user entering the firstinstant messaging entity and the second instant messaging entity intothe calendar event. Recognizing the first instant messaging entity andthe second instant messaging entity as invitees may be performed inresponse to a user selecting the first instant messaging entity and thesecond instant messaging entity from a list of potential instantmessaging entities, the list being generated by the calendarapplication.

Recognizing the first instant messaging entity and the second instantmessaging entity as invitees may be performed in response to a userdragging and dropping a block of time from the calendar application to arepresentation of the first instant messaging entity and arepresentation of the second instant messaging entity. Enabling usergeneration of electronic content may include providing the calendarevent, in which the user may generate electronic content, the calendarevent being provided in response to the dragging and dropping, with thefirst instant messaging entity and the second instant messaging entityas invitees.

Recognizing the first instant messaging entity and the second instantmessaging entity as invitees may be performed in response to a userselecting a feature associated with the first instant messaging entityand the second instant messaging entity, the feature automaticallyinviting the first instant messaging entity and the second instantmessaging entity to the calendar event. Recognizing the first instantmessaging entity and the second instant messaging entity occurs beforeenabling user generation of the electronic content.

Recognizing the first instant messaging entity and the second instantmessaging entity may be performed in response to the user dragging arepresentation of the first instant messaging entity and arepresentation of the second instant messaging entity to arepresentation of the electronic content. Recognizing the first instantmessaging entity and the second instant messaging entity may beperformed in response to the user dragging a representation of theelectronic content to a representation of the first instant messagingentity and a representation of the second instant messaging entity.

The first instant messaging entity or the second instant messagingentity may represent an individual user of an instant messaging system.The first instant messaging entity or the second instant messagingentity may represent multiple users of an instant messaging system. Thefirst instant messaging entity or the second instant messaging entitymay be listed in a buddy list. The message may be an instant messagethat may be sent to multiple instant messaging entities at substantiallythe same time.

The electronic content may be modified as indicated in the response toproduce modified electronic content. A new message including themodified electronic content may be generated, the new message beingassociated with the first instant messaging entity and the secondinstant messaging entity. The user may be enabled to send the newmessage as an instant message to the first instant messaging entity andthe second instant messaging entity using the application.

In another general aspect, a method of sharing electronic contentincludes enabling access to user designation of contacts for whompresence is maintained. User selection of one or more of the contacts isenabled, and user selection of a first contact and a second contact fromthe contacts is recognized. An electronic message associatedelectronically with the first contact and the second contact asrecipients is accessed. The electronic message is sent to each of thefirst contact and the second contact using an instant messaging system.

Implementations may include one or more of the following features. Forexample, sending the electronic message may be in response to a singleuser instruction. Enabling user description, enabling user selection,recognizing user selection, accessing the electronic message, andsending the electronic message may be each performed by an instantmessaging application. The electronic message may include an invitationto a calendar event. Accessing the electronic message may includeaccessing the invitation, and sending the electronic message may includesending the invitation.

In another general aspect, an apparatus comprising a computer readablemedium having instructions stored thereon that when executed by amachine result in at least enabling access to user designation ofcontacts for whom presence is maintained and enabling user selection ofone or more of the contacts. User selection of a first contact and asecond contact from the contacts is recognized. An electronic messageassociated electronically with the first contact and the second contactas recipients is accessed. The electronic message is sent to each of thefirst contact and the second contact using an instant messaging system.

In another general aspect, an apparatus comprising a computer readablemedium having instructions stored thereon that when executed by amachine result in at least enabling user generation by an application ofelectronic content to be shared with at least a first recipient and asecond recipient using an instant messaging system. User selection of afirst instant messaging entity as the first recipient and a secondinstant messaging entity as the second recipient is recognized by theapplication. A message including the electronic content is generated,the message being associated with the first instant messaging entity andthe second instant messaging entity. The user is enabled to send themessage as an instant message that is sent concurrently to the firstinstant messaging entity and the second instant messaging entity usingthe application. A response to the message is received from the firstinstant messaging entity that is not sent to the second instantmessaging entity or from the second instant messaging entity that is notsent to the first instant messaging entity.

DETAILED DESCRIPTION

Scheduling an event may demand the attention of all the people that areto attend the event. Each person that is to attend the event may need todetermine his or her availability to attend the event and, if necessary,determine and communicate changes that need to be made to the event suchthat attendance is possible. Various types of communication may be usedto invite the proposed attendees (i.e., the invitees) to the event,including e-mail. Another type of communication that may be used is aninstant messaging (IM) system. The instant messaging system mayautomatically display the invitation on the screens of the invitees,immediately bringing the invitation to the attention of the invitees.Use of an IM system may allow an invitor to receive prompt responses totheir invitation, while providing some level of assurance to the invitorthat the invitee perceives their invitation without undue delay.

One implementation involves scheduling an event among a set of peopleusing a combination of a calendar application and an IM system. Thecalendar application enables the storage, creation, and modification ofevents that a person is scheduled to attend. The calendar applicationalso displays pending but unconfirmed events for review. The IM systemmay be used to send invitations to a proposed event, to suggest changesto the proposed event, and to inform invitees to the proposed event ofchanges to the proposed event.

In the above implementation, the person that originally proposed theevent may have the names of one or more invitees stored in a buddy list,and thus may leverage the buddy list in selecting invitees and invokingcalendar invitations. For example, the person originally scheduling theevent may drag and drop a representation of a calendar event from thecalendar application over a name or group of names in the buddy list,such that identification and contact information for the buddy listinvitees may be added to or referenced by the calendar event and aninstant message and/or e-mail message invitation or an alert may beinspired from the invitor to the invitee(s). Similarly, a name or groupof names from the buddy list may be dragged and dropped over arepresentation of a calendar event from the calendar application. Asanother example, a blank period of time from the calendar applicationalso may be dragged and dropped over a name or group of names in thebuddy list to select the name or group of names as invitees to anunspecified event that will occur during the blank period of time.Likewise, a name or group of names from the buddy list also may bedragged and dropped over a blank period of time to create a new eventduring the blank period of time with the name or group of names asinvitees to the event. As yet another example, the names of the peopleto be invited to the event may be typed or chosen from a list in thecalendar application.

More particularly, in the above implementation, after the particularusers of the IM system have been selected as invitees to the event, aninvitation is sent to the selected users. The invitation may include adescription of the event with a proposed time and date for the event.The communication of this invitation may be used to inspire creation ofa corresponding calendar event entry in the calendar application foreach of the invitees and to inspire an alert regarding conflictingcalendar entries for the invitee.

An invitee may suggest a change to the proposed event, for example, whena conflict exists between the proposed event and another event storedwithin the calendar application for the invitee. The invitation to theproposed event may include a form that the invitees may use to requestchanges in the proposed event, and the form may propagate to the otherinvitees. Such requested changes may be approved by the user thatoriginally proposed the event before they are propagated to theinvitees. Once propagated, changes to the event may be automaticallyentered into the calendar application for all the invitees, and/ornotifications may be sent to each invitee of proposed changes to enabletheir confirmation of availability/acceptance or alternatively theirproposal for further modification to the event.

By receiving invitations over the IM system, the invitees may benotified without delay of invitations, enabling them to respondimmediately. Moreover, invitees may promptly communicate and resolveconflicts.

Furthermore, by sending invitations over the IM system, the invitor mayprovide notification of an event without delay. Thus, invitors areprovided a convenient, simple, and quick manner to inspire creation ofan event with selected invitee(s), as well as a convenient manner ofselecting the invitees. For example, to inspire creation of an event, aninvitor may conveniently copy a selected time slot(s) and paste using acommand, such as, for example, <control><c>, the copied time slot(s) toone or more buddies, or other contacts. Invitee(s) may be selected, forexample, by pasting the copied time slot on a buddy (or other invitee),by preselecting one or more buddies using, for example, a left-click ona mouse for a single buddy or <shift> click for multiple buddies andpasting the copied time slot(s) onto the selected buddy(ies). Draggingand dropping also may be used in lieu of, or in addition to copying andpasting. Dragging a time slot or event over a buddy also mayautomatically select (e.g., highlight) that buddy. Invitees may beselected for an existing calendar event in an analogous manner toselecting invitees to a newly inspired event, for example, bycopying/pasting or dragging/dropping the existing event.

As suggested above, enabling selection of the invitees and the eventitself quickly by dragging and dropping between an electronic calendarand a buddy list may save time in creating/updating an event. Draggingand dropping may automatically specify certain details of the event,eliminating the need to enter those details, and thereby saving time.For example, simply dragging a time slot to a group of buddies (or othercontacts) automatically specified the time, day, duration, and multipleinvitees for an event.

Referring to FIG. 1, an implementation of a networked computingenvironment 100 supports communications between computer users. Thenetworked computing environment 100 facilitates communication forscheduling an event among multiple users of the networked computingenvironment 100. The networked computing environment 100 is used todistribute messages that aid in the scheduling and modification of theevent.

Users of the networked computing environment 100 are distributedgeographically and communicate using client systems 110. The clientsystems 110 are shown including a calendar application 112 and an IMapplication 114, although other client systems that do not includeapplications 112 or 114 may be used. A network 120 interconnects theclient systems 110. The client systems 110 are connected to network 120through various communication media 125, such as a modem connected to atelephone line (using, for example, serial line internet protocol (SLIP)or point-to-point protocol (PPP)) or a direct network connection (using,for example, transmission control protocol/internet protocol (TCP/IP)).A host server 130 also may be connected to the network 120 and may beused to facilitate some direct or indirect communications between theclient systems 110.

Each of the client systems 110 may operate the calendar application 112that enables a user to schedule events for attendance by multiple usersof the networked computing environment 100. The client system 110 alsomay operate the IM 114 application that allows a user of the clientsystem 110 to communicate with the other users of the networkedcomputing environment 100. Each instance of the IM application 114 mayhave an associated buddy list that includes the users of the IM systemthat may be invited to an event. A user of the IM application 114 maycreate a calendar event using the calendar application 112 and theninvite other users to the event using the IM application 114. Thecalendar application 112 may facilitate specification of the details ofthe event, such as a date and a time for the event, while the IMapplication 114 may facilitate selection of a set of users to be invitedto the event and invitation of the users to the event.

Referring to FIG. 2, one implementation of a buddy list interface 200may be used with one or more of the systems described herein to display,for a given user, identifiers (e.g., screen names) for other users whomthey have selected for presence monitoring. The other users that havebeen selected for presence monitoring are logically grouped to form abuddy list for the given user. The buddy list interface 200 enablesdesignation by the given user of others to invite to the proposedcalendar event through selection of their identifiers or screen namesusing the given user's buddy list.

The buddy list interface 200 contains a text box 202 that contains thebuddy list for the given user, who is identified in the title bar 203 bya screen name “AOL User.” The buddy list includes multiple screen names.The buddy list in the buddy list interface 200 includes the screen name204 a, “randomcontact2”; the screen name 204 b, “Boss”; the screen name204 c, “Mom”; the screen name 204 d, “Dad”; and the screen name 204 e,“Brother.”

The buddy list in the buddy list interface 200 separates the constituentscreen names 204 a-204 e into multiple buddy groups 206 a-d.Specifically, the buddy list includes a buddy group 206 a, “Buddies”; abuddy group 206 b, “Co-Workers”; a buddy group 206 c, “Family”; and abuddy group 206 d, “Offline,” that includes the screen names in thebuddy list that are not connected to the IM system at any given instantin time. The screen name 204 a appears below the heading for the buddygroup 206 a because the screen name 204 a has been placed in the buddygroup 206 a and the corresponding user (randomcontact2) is logged in tothe IM system. The heading for each of the buddy groups 206 a-dindicates the total number of buddies in the group, as well as thenumber of buddies who are included in the group who presently are loggedinto the IM system-those who are “present.” For example, one out of theten members of the buddy group 206 a is logged in to the IN system. Thebuddy list interface 200 contains a “Setup” button 208 that, whenselected, enables the user to modify screen names included within thedisplayed buddy list.

Referring to FIG. 3, one implementation of an electronic calendarinterface 300 for use with one or more of the systems described hereindisplays electronic calendar events from a calendar of a given user fora selected month. The electronic calendar interface 300 includesmultiple events 302 a-e scheduled occur during the displayed month. Forexample, the electronic calendar interface 300 displays an event 302 atitled “code review,” an event 302 b titled “client demo,” an event 302c titled “design meeting,” an event 302 d titled “birthday dinner,” andan event 302 e titled “happy hour.” The location of each of the events302 a-e within the electronic calendar interface 300 indicates the dayon which the event 302 a-e occurs. For example, the event 302 a occurson the sixth day of the displayed month. The electronic calendarinterface 300 also includes blank periods 304 a during which no eventsare scheduled. The blank periods 304 a represent a full day during whichno events occur.

Events may be added to the month currently displayed by the electroniccalendar interface 300 through the use of an interface displayed as aresult of selecting an “Add Event” button 306 or an “Add Task” 308.Selecting the “Add Event” button 306 causes an interface to be displayedfor specifying an event that is to be added to the user's calendar.Selecting the “Add Task” button 308 causes an interface to be displayedfor specifying a particular type of event, that is, a task, that is tobe added to the user's calendar.

The electronic calendar interface 300 also includes tabs 310-314 thatmay be used to select the desired view. A month tab 310 has beenselected, as evidenced by the highlighted appearance of the tab, so theevents occurring during a single month are displayed. Selecting a weektab 312 causes the electronic calendar interface 300 to display only theevents occurring during a selected week, as described with reference toFIG. 4. Similarly, selecting a day tab 314 causes the electroniccalendar interface 300 to display only the events occurring on aselected day, as described with reference to FIG. 5.

Referring to FIG. 4, the week tab 312 on the electronic calendarinterface 300 has been selected, as evidenced by the highlightedappearance of the tab 312. Consequently, the events that occur during aselected week are displayed in FIG. 4. Because the week of Oct. 5, 2003is selected for presentation in the “week” view of FIG. 4, and becausethe events 302 a-e occur during the week of Oct. 5, 2003, the events 302a-e are displayed on the electronic calendar interface 300. The locationand size of each of the events 302 a-e within the electronic calendarinterface 300 indicate the date, time, and duration of the event. Forexample, the event 302 e occurs on the tenth day of the month, which isa Friday, from 4 PM to 5 PM. The electronic calendar interface 300 alsoincludes blank periods 304 b during which no events are scheduled. Theblank periods 304 b represent hours within the displayed week duringwhich no events are scheduled to occur. The tabs 310-314 remainavailable to specify the desired view.

Referring to FIG. 5, the day tab 314 on the electronic calendarinterface 300 has been selected, as evidenced by the highlightedappearance of the tab 314. Consequently, the events that occur during aselected day are displayed in FIG. 5. Because the day of Oct. 8, 2003 isselected for presentation in the “day” view of FIG. 5, and because theevents 302 b-d occur during the day of Oct. 8, 2003, the events 302 b-dare displayed on the electronic calendar interface 300. The location andsize of each of the events 302 b-d within the electronic calendarinterface indicate the time and duration of the event. For example, theevent 302 d occurs between 6 PM and 8 PM on the displayed day. Theelectronic calendar interface 300 also includes blank periods 304 cduring which no events are scheduled. The blank periods 304 c representhours within the displayed day during which no events are scheduled tooccur. The tabs 310-314 remain available to specify the desired view.

Referring to FIG. 6, one implementation of the electronic calendarinterface 300 for use with one or more of the systems described hereinincludes an event specification tool 600 that enables the specificationof new events to be added to the calendar. The event specification tool600 is displayed after the “Add Event” button 306 or the “Add Task”button 308 from FIG. 3 is selected. A descriptive title for the newevent may be entered into a title text field 602, and a date for the newevent may be specified in a date text field 604. Time selection boxes606 may be used to select the time of the event, and a durationselection box 608 may be used to specify the length of the event. A typefor the new event may be chosen from a type selection box 610. Forexample, an event may be categorized as an appointment, a businessmeeting, a lunch, a personal meeting, or some other category, includingboth standard categories provided by a calendar system and user-definedcategories.

In one implementation, conflicts between the new event and eventsalready existing in the calendar may be displayed on the eventsspecification tool 600 in a conflicts text box 612. The conflicts textbox 612 will list events in the calendar that conflict with the newevent, and the list may be produced by selecting a conflict check button614. If no events in the calendar conflict with the new event, then theconflicts text box 612 may include the text “No Conflicts.” The detailsof the new event specified in text boxes 602 and 604 and selection boxes606-610 may be changed to eliminate one or more conflicts listed in theconflicts text box 612.

In another implementation, other people may be invited to the new event.Selecting a sharing link 616 may display a tool (see FIG. 7) forchoosing the people that are to be invited to the new event.

In another implementation, the event specification tool 600 also enablesthe modification of existing events. The tool 600 may be presented foran existing event with the details of the existing event alreadyspecified.

Any changes made to the details of a new event or an existing event maybe saved by selecting a save button 618. An existing event also may bedeleted from the calendar through use of a delete button 620. Anychanges made to the details of a new event or an existing event may beundone and discarded by selecting a cancel button 622.

Referring to FIG. 7, an implementation of the electronic calendarinterface 300 also may include a mechanism for specifying the people tobe invited to an event. An invitation tool 700 for specifying inviteesto an event may be displayed after the sharing link 616 from FIG. 6 isselected from the event specification tool 600 for an event. Invitees tothe event may be chosen from a possible invitee list 702 that mayinclude all possible invitees to the event. The names of invitees alsomay be entered manually into an invitee text box 704.

In one implementation, selecting an add button 706 after one or moreinvitees have been selected from the possible invitee list 702 orentered into the invitee text box 704 adds the selected or entered namesto the set of people that are to be invited to the event for which theinvitation tool 700 was displayed. Alternatively or additionally, allnames included in the possible invitee list 702 may be added to the setof invited people by selecting an “Add All” button 708.

In another implementation, the names of the people added to the set ofpeople to be invited may be listed in a selected invitee list 710.Invitees may be removed from the selected invitee list, and additionallyor consequently from the set of people to be invited to the event, byselecting a remove button 712.

An invitation may be sent to each of the people with names listed in theselected invitee list 710 by selecting a share button 714. Any changesmade to the set of people to be invited may be undone and discardedthrough use of a cancel button 716.

Referring to FIG. 8, a process 800 allows a user to invite invitees toan event. The process 800 may involve use of one or more of the buddylist interface 200 from FIG. 2, the electronic calendar interface 300from FIGS. 3-5, and the associated tools 600 and 700 from FIGS. 6 and 7.For example, the process 800 may be used to invite people listed on thebuddy list interface 200 to an event created within the electroniccalendar interface 300.

The process 800 includes creating an event using, for example, the eventspecification tool 600 (802). Creating the event may include, forexample, providing information for one or more of the boxes 602-610. Theprocess 800 also includes selecting IM entities to invite to the event(804). IM entities may include, for example, (i) individuals, such as,for example, individual buddies, (ii) groups of individuals, such as,for example, a buddy group, or (iii) organizations, where each IM entityhas an IM screen name or other IM account identifier.

IM entities may be selected (804) in various ways. For example, theinvitor may use an invitation interface to enter IM entities to beinvited to the event (804 a). An invitation interface may be, forexample, the invitation tool 700, and in one implementation of theprocess 800, the invitor may select the sharing link 616 in conjunctionwith (before, during, or after) creating the event (802). Upon selectingthe sharing link 616, the invitation tool 700 is displayed and IMentities may be selected or entered, for example, in one or more of theinvitee lists, as explained in the discussion of the invitation tool700.

As another example of selecting IM entities (804), the invitor mayselect IM entities in various ways and drag the selected IM entities tothe event to which the selected IM entities are to be invited (804 b).In one implementation of the process 800, the IM entities are selectedfrom a buddy list included in the buddy list interface 200. The selectedentities may be dragged from the buddy list interface to arepresentation of the event included, for example, in at least one ofthe month, the week, or the day views of the electronic calendarinterface 300. The representation of the event also may be afree-standing icon, for example. The action of dragging the IM entitiesto the event, or dragging and dropping, selects the IM entities asinvitees to the event.

As yet another example of selecting IM entities (804), the invitor mayselect and drag the event to the IM entities to be invited to the event(804 c). In one implementation of the process 800, a representation ofthe event is included in at least one of the month, the week, or the dayviews of the electronic calendar interface 300. The event is draggedfrom the electronic calendar interface 300 to the names of the IMentities to be invited to the event included in the buddy list interface200. The action of dragging the event to the IM entities, or draggingand dropping, selects the IM entities as invitees to the event.

After IM entities have been selected as invitees to the event (804),other details of the event optionally may be specified (806). Forexample, one or more of the fields in the event specification tool 600may not have been filled-in or may need to be modified. After the eventcreator is satisfied with the event, an invitation to the event is sentto the selected IM entities (808). The invitation is in the form, forexample, of an instant message. If an IM entity is not available toreceive an instant message, then an e-mail message, or some other formof communication, may be sent automatically to the IM entity. Theinstant message may include, for example, a description of the proposedevent and a link that, when selected, causes the event to be added tothe calendar of the IM entity that received the invitation. The instantmessage also may include a form with which changes to the detailsspecifying the event may be suggested and sent to the event creator and,optionally, other invitees. Changes may be suggested so as, for example,to avoid a conflict. In one implementation, the electronic calendarinterface 300 is used to create an event, and the calendar application112 sends the event to the IM application 114 for sending invitationIMs. The IM application 114 packages the information in an instantmessage to be sent to the IM entities. The packaging of the invitationIMs designates the IM as including an invitation to a calendar event andincludes the event information in a specified format. Upon receipt ofthe invitation IM at another system, the IM application 114 on thatother system recognizes the destination an inserts a link to a script orother routine for loading the event into the local calendar application112. The packaging of the invitation IMs also includes a form that canbe used to suggest changes. The form may be preloaded with the eventinformation and may be opened within the IM application 114 or thecalendar application 112 on that other system, or using some otherapplication. The form also includes a mechanism for sending the formback to the invitor.

The invitation is received by an invited IM entity and a determinationis made as to whether the event is acceptable (809). The determinationmay be manual if, for example, the invited IM entity objects to theevent, or the determination may be automatic if, for example, there is atime conflict. If the event is acceptable, the invited IM entity sends aconfirmation, which the event creator receives (816). If the event isnot acceptable, then the invited IM entity sends suggested changes. Anysuggested changes sent to the event creator may be received in, forexample, an instant message (810), and the event may be modifiedaccordingly (812). An updated invitation may be sent to notify all ofthe invited IM entities of the changes that have been proposed to theevent (814), and the invited IM entity again determines if the (nowmodified) event is acceptable (809). As described in the discussion ofFIGS. 12A-12M, the invitation displayed for the IM entities may beupdated each time a change to the proposed event is made and propagated.Further, if an invitee has already accepted an event before all changeshave been made to the event, the invitee may be notified of theadditional changes made since the invitee accepted the event.

When an invitee accepts the invitation to the event, a confirmation tothe invitation is sent to the event creator. The event creator thenreceives one or more confirmations (816). In one implementation, instantmessages including reminders of the event are sent as the time for theevent approaches.

Referring to FIG. 9, a scheduling process 900 may occur between aninvitor 902 and an invitee 904 that is to be invited to an event createdby the invitor 902. The process 900 begins when the invitor 902 createsan event within, for example, an electronic calendar application, using,for example, the electronic calendar interface 300 from FIGS. 3-5 (906).The invitor 902 then selects the IM entities to be invited to the event(908). An instant message is sent from the invitor 902 to the selectedIM entities, including the invitee 904, inviting the selected IMentities to the event (910). If the invitee 904 is not able to receivean instant message from the invitor 902, then an e-mail message, orother form of communication, may be sent from the invitee 904 to theinvitor 902.

The invitor 902 knows when the invitee 904 is unable to receive aninstant message from the invitor 902 based on a lack of presencedisplayed for the invitee 904 in a buddy list associated with theinvitor 902. For example, the name of the invitee 904 may be included inthe offline buddy group 206 d from FIG. 2. When it is determined thatthe invitee 904 is unavailable, the invitor 902 may manually create andsend the e-mail message to the invitee 904. Additionally oralternatively, the e-mail message may be created and sent automaticallywhen the name of the invitee 904 is found in the offline buddy group 206d based on an e-mail address that has been associated with the name ofthe invitee 904.

In another implementation, if the invitee 904 is unable to receive aninstant message from the invitor 902, then an instant message includingthe invitation may be placed in a queue of instant messages to be sentto the invitee 904 when the invitee 904 becomes available to receiveinstant messages. For example, the instant messages may be sent to theinvitee 904 as soon as the invitee 904 next logs in to the IM system.While the instant message remains in the queue of instant messages to besent to the invitee 904, the invitor 902 may be presented with anindication that the invitation has not been seen or confirmed by theinvitee 904.

The queue may be used to store instant messages sent to the invitee 904while the invitee 904 is unable to receive the instant messages. Forexample, the queued instant messages may include invitations to calendarevents that are proposed while the invitee 904 is unable to receiveinstant messages. The queue may be stored on a computer that the invitee904 uses to access the IM system, such as the client system 110 of FIG.1, or otherwise. The queue also may be stored on a server of the IMsystem that is accessed by the invitee 904, such as the host server 130of FIG. 1. The server may store one queue for each user of the IMsystem.

The queue for the invitee 904 may be monitored to prevent for example,burdening the invitee 904 with invitations to events that have alreadypassed. For example, invitations to events that have already happenedmay be deleted from the queue periodically or in response to some event,such as the occurrence of an event for which an invitation has beenplaced in the queue. As another example, as an invitation is removedfrom the queue for delivery to the invitee 904, the date of the eventfor which the invitation is sent may be checked to confirm that the datehas not already passed. If the date has not passed, then the invitationis delivered to the invitee 904, and if the date has passed, then theinvitation is removed from the queue and not delivered to the invitee904.

In yet another implementation, an e-mail message including an invitationto the event may be created and sent automatically to the invitee 904and an alert of the e-mail message may be placed in a queue of instantmessages to be sent to the invitee 904 when the invitee 904 next becomesavailable to receive instant messages. The queue in which the alert isplaced may be the same queue in which other instant messages, includinginvitations to events, are queued for the invitee 904. When the invitee904 is next available to receive instant messages, the invitee 904 issent the alert. The alert may, for example, automatically take theinvitee 904 to the e-mail message and enable the invitee 904 to acceptor suggest changes to the proposed event, provide a link to the e-mailmessage, or merely alert the invitee 904 to the existence of the e-mailmessage. If the invitee 904 views the e-mail message before the alert issent to and viewed by the invitee 904, then the alert is removed fromthe queue of instant messages. While the alert remains in the queue ofinstant messages to be sent to the invitee 904, the invitor 902 may bepresented with an indication that the invitation has not been seen orconfirmed.

By way of example, the invitor 902 may select five IM entities to beinvited to the event. Of the five IM entities, two may be online andavailable to receive instant messages from the invitor 902. Those two IMentities, of which the invitee 904 is one, are sent invitations to theevent in instant messages that are immediately received. The other threeIM entities may not be available to receive instant messages. Of thosethree IM entities, one may have specified that instant messageinvitations to events be queued and delivered the next time the IMentity is available to receive instant messages, so an invitation issent and queued for later delivery to the IM entity. The remaining twoIM entities may have specified that e-mail invitations be sent when theIM entities are not available to receive instant messages and thatinstant messages alerts of the e-mail invitations be queued for deliverywhen each of the IM entities next becomes available to receive instantmessages. As such, e-mail invitations are sent to and instant messagealerts of the e-mail invitations are queued for the remaining two IMentities. One of the two IM entities receives the e-mail message beforebecoming available to receive instant messages, so the instant messagealert is removed from the queue of instant messages for that IM entity.The other IM entity logs in to the IM system and receives the alert,which takes the IM entity to the e-mail invitation.

In instances where the invitee 904 is available to receive an instantmessage by the invitor 902, the invitee 904 receives the instant messagesent by the invitor 902 (912). The invitee 904 enters the eventdescribed in the invitation into an electronic calendar application thatstores events for the invitee 904 (914). A determination is made, eithermanually or by the electronic calendar application, as to whether theevent to which the invitee 904 was just invited conflicts with otherevents stored by the electronic calendar application (916). If the eventdoes create a conflict with the previously stored events, then theinvitee 904 determines what changes need to be made to the event for theinvitee 904 to attend. These changes are suggested to the invitor 902 inan instant message (918).

The suggested changes are received by the invitor 902 (920), and theinvitor 902 modifies the event according to the suggested changesreceived from the invitee 904 (922). The invitor 902 sends a new instantmessage to the invited IM entities, including the invitee 904, notifyingthe invited IM entities of the changes that have been made to the event(924).

The new instant message outlining the changes is received by the invitee904 (926). The invitee 904 modifies the event stored in the electroniccalendar application (928). The modification may be made automaticallyor in response to the invitee 904 accepting the proposed changes. Adetermination is made again as to whether the event conflicts withevents already stored by the electronic calendar application (916). If aconflict is found, then the process of modifying the event according tosuggested changes is repeated. If no conflict is found (on thisiteration through operation 916 or the earlier iteration), then theinvitee 904 sends a confirmation to the invitor 902 (930), and theinvitor 902 receives the confirmation (932).

When the invitee 904 is sent an invitation to the event in an e-mailmessage while other invitees are sent the invitation in an instantmessage, the invitee 904 may participate in the process of updating theevent in various ways. In one implementation, the other invitees maymodify the event, and the invitee 904 may receive a second e-mailmessage outlining the changes made to the event after the changes areagreed upon by all of the invitees (912-932). In another implementation,the invitee 904 may receive a new e-mail message after every change thatis accepted or made by the invitor 902. Each e-mail message may includea single button that may be used to send a communication (likely ane-mail) to the invitor 902 and/or the entire group of invitees so thatthe invitee 904 may participate in the process of changing the eventwhenever the invitee 904 receives an invitation.

Referring to FIG. 10, a process 1000 may be used to specify the inviteesto an event before details of the event itself are specified. In otherwords, the IM entities to be invited to the event may be selected beforethe event is created (1010). After the IM entities to be invited to theevent have been chosen, the details of the event to which the IMentities are to be invited are specified (1020). Referring again toFIGS. 2-5, in one implementation of the process 1000, selection (1010)includes dragging and dropping a representation of a blank period oftime in the electronic calendar interface 300 during which the proposedevent is to occur over a screen name or group name (or a pre-selectedset of names) from the buddy list interface 200. For example, the IMentity with the screen name 204 a (FIG. 2) may be selected as an inviteeto an event to occur during the blank period 304 a (FIG. 3) by havingboth the buddy list interface 200 and the calendar interface 300 open ona desktop of a computer display, and dragging and dropping the blankperiod 304 a over the screen name 204 a. In other implementations the IMentities may be selected from a list or other interface, such as, forexample, the invitation tool 700.

In further implementations, selection (1010) may include dragging anddropping, for example, a group name (or a pre-selected set of names) inthe buddy list interface 200 over a representation of the blank periodof time during which the proposed event is to occur from the electroniccalendar interface 300. For example, the buddy group “Family” 206 c maybe selected as an invitee to an event to occur during the blank period304 a by dragging and dropping the buddy group “Family 206 c over theblank period 304 a.

Referring to FIG. 11, a process 1100 enables collaborative scheduling ofelectronic calendar events among a set of IM entities. The process 1100enables, for example, implementations of the processes 800 and 900 fromFIGS. 8 and 9. The process 1100 may be performed, for example, by aclient system 110 or a host server 130, alone or in combination.

The process 1100 includes providing a calendar event from an electroniccalendar application, such as, for example, the electronic calendarinterface 300 (1102). The calendar event may be provided, for example,in response to a user request for creation of a new calendar event. AnIM entity is recognized by the calendar application as an invitee to theevent (1104). In one implementation, recognizing an IM entity as aninvitee to the event includes recognizing when an existing event or ablank period in the calendar application has been dragged over the nameof the IM entity. In another implementation, recognizing the IM entityas an invitee includes recognizing when the IM entity is selected from alist of IM entities. In a further implementation, recognizing the IMentity includes recognizing when the IM entity has been entered into anarea for specifying invitees to the event. Note that several of theseimplementations reverse the order of operations 1102 and 1104 by usingblank periods for which no event has yet been created.

If necessary, the details of the event are set in the calendarapplication to user specified values, possibly including default values(1106), and an invitation to the event is generated (1108). Theinvitation is sent to the IM entity (the invitee) using, for example, aninstant message (1110). If the IM entity is not able to receive instantmessages, then the invitation may be sent to the IM entity using ane-mail message or other form of communication. The IM entity may suggestchanges to the details of the event due to conflicts, for example,between the event and other events of the IM entity, and the changes maybe received (1112). The details of the event may be reset according tothe suggested changes (1114), and an updated invitation to the event maybe generated (1116). The updated invitation may be sent to the IM entity(1118). If the IM entity does not find any conflicts between the updatedevent and other events stored for the IM entity, then the IM entitysends a confirmation to the invitation, which is then received (1120).In one implementation, instant message reminders may be sent to the IMentity as the time of the event approaches.

As explained in more detail below, FIGS. 12A-12M illustrate operationsthat may be experienced in one implementation of the above concepts. Theoperations include inviting an invitee to a calendar event and receivingfeedback from the invitee.

Referring to FIG. 12A, while collaboratively scheduling calendar events,a user with a screen name AOL User interacts with the buddy listinterface 200 and the electronic calendar interface 300. The buddy listinterface 200 and the electronic calendar interface 300 may be displayedsuch that the user sees both the buddy list interface 200 and theelectronic calendar interface 300 at the same time. One or more screennames may be selected in the buddy list interface 200, although none isshown as being selected in the buddy list 200 of FIG. 12A. Theelectronic calendar interface 300 may include one or more calendarevents. For example, the calendar interface 300 includes a calendarevent 302 a. As indicated by the bold outline around the calendar event302 a, the calendar event 302 a has been selected. A mouse pointer 1205may be used to select the calendar event 302 a, or a screen name.

Referring to FIG. 12B, the event 302 a has been selected from theelectronic calendar interface 300 and is being dragged with the mousepointer 1205. As indicated by an arrow 1210, the event 302 a is beingdragged towards the buddy list interface 200. Referring to FIG. 12C, theevent 302 a has been dragged from the electronic calendar interface 300over the screen name 204 a, “randomcontact2,” in the buddy listinterface 200, thereby selecting the screen name 204 a as an invitee tothe calendar event 302 a. The selection of screen name 204 a is shown bythe highlighting of the screen name 204 a in FIG. 12C.

Referring to FIG. 12D, by dropping the event 302 a onto the screen name204 a, the screen name 204 a has been entered automatically in theselected invitee list 710 of the invitation tool 700 that is displayedalong with the event specification tool 600 for the calendar event 302a. An invitation to the event 302 a may be sent to randomcontact2through selection of the share button 714, which sends an invitation inan instant message.

Referring to FIG. 12E, one implementation of an instant message 1208 isshown, such as might be sent through selection of the share button 714.The instant message 1208 includes a “To” field 1208 a indicating thatthe instant message is for randomcontact2, a body field 1208 b includinga description of the calendar event, and a send button 1208 c. Selectingthe send button 1208 c sends the description of the calendar event inthe body field 1208 b to the recipient(s) of the instant messagespecified in the “To” field 1208 a. In another implementation, theinstant message 1208 may not be shown, and the instant message invitingrandomcontact2 to the event may be sent automatically and transparentlyafter the share button 714 has been selected.

Referring to FIG. 12F, the instant message 1208 has been received andthe event specification tool 600 has been opened for the proposed eventto which randomcontact2 has been invited.

The event specification tool 600 may be opened automatically by, forexample, the IM system for randomcontact2 (i) recognizing that thereceived IM 1208 is an invitation to a calendar event, and (ii) causinga calendar application to open and display the event data in the tool600. The event specification tool may be opened manually by, forexample, the user randomcontact2 reading the received IM 1208 andselecting an embedded command that causes the tool 600 to open.

The event specification tool 600 may include an accept button 1210, theselection of which includes the event 302 a in the electronic calendarinterface 300 for randomcontact2. The electronic calendar interface 300for randomcontact2 is shown in the background with the event 302 aincluded, such as would occur after selecting the accept button 1210.Randomcontact2 also may modify the details of the event specified in theevent specification tool 600 by directly changing the entries displayed.Such changes may be based on, for example, conflicts with other events.For example, randomcontact2 may change the date of the event specifiedin the date text field 604. After making the desired changes to theevent, randomcontact2 may notify AOL User, who originally proposed theevent, of the changes through selection of a modify button 1215.Selecting the modify button 1215 sends an instant message to AOL Userdescribing the changes made by randomcontact2 to the proposed event. Forexample, randomcontact2 may propose a date change for the event 302 afrom Oct. 6, 2003 to Oct. 7, 2003 by modifying the date text field 604and selecting the modify button 1215. An IM would be sent back to AOLUser to inform AOL user of the proposed date change.

Referring to FIG. 12G the event specification tool 600 for AOL User isshown displaying the data for the event 302 a and highlighting thechanges proposed by randomcontact2. Note that the calendar interface 300for AOL User is also displayed for the convenience of AOL User. Thereceived instant message may, for example, cause the event specificationtool 600 for AOL User to open automatically. The details of the event302 a may be further modified by AOL User with the event specificationtool 600. Selecting a share button 1220 once again sends an updatedinvitation in an instant message to randomcontact2. In this manner, theevent 302 a may be modified until the details of the event 302 a areagreed upon by AOL User and randomcontact2.

Referring to FIG. 12H, the user with the screen name “AOL User” mayinvite multiple invitees to an event. The user may select the event 302a in the calendar interface 300 and select multiple screen names in thebuddy list interface 200. For example, in the buddy list interface 200,the screen names 204 a (“randomcontact2”), 204 c (“Mom”), 204 d (“Dad”),and 204 e (“Brother”) have been selected.

Referring to FIG. 12I, the user may then drag the event 302 a towardsthe buddy list interface 200, where the screen names 204 a and 204 c-204e are selected, as indicated by an arrow 1230. Referring to FIG. 12J,the event 302 a has been dragged from the electronic calendar interface300 over one of the screen names 204 a and 204 c-204 e in the buddy listinterface 200, thereby selecting the screen names 204 a and 204 c-204 eas invitees to the calendar event 302 a.

Referring to FIG. 12K, after dropping the dragged event 302 a onto thebuddy list interface 200, the screen names 204 a and 204 c-204 e areentered automatically in the selected invitee list 710 of the invitationtool 700 that is displayed along with the event specification tool 600for the calendar event 302 a. The event may be shared withrandomcontact2, Mom, Dad, and Brother through selection of the sharebutton 714, which sends an invitation in a separate instant message toeach of randomcontact2, Mom, Dad, and Brother.

Referring to FIG. 12L, separate IMs 1232 1234, 1236, and 1238 are shownfor each of randomcontact2, Mom, Dad, and Brother, respectively. TheseIMs 1232, 1234, 1236, and 1238 may, for example, be processed in amanner similar to IM 1208. In particular, each of randomcontact2, Mom,Dad, and Brother may make changes to the event as described above withrespect to FIG. 12F, and AOL User may accept the changes and/or makefurther changes as described with respect to FIG. 12G. In anotherimplementation, the instant messages 1230, 1232, 1234, and 1236 may notbe shown, and the instant messages inviting randomcontact2, Mom, Dad,and Brother to the event may be sent automatically and transparentlyafter the share button 714 has been selected. AOL User also may drag anddrop the event 302 a into a buddy group name, such as, for example,“Family,” to invite multiple entities to the event 302 a.

Referring to FIG. 12M, a buddy chat window 1240 enables simultaneoussending of an invitation to the selected event to the selected screennames. The invitor, AOLUser, may be given the option of using multipleinstant messages, as was done with respect to FIG. 12L, or a singlebuddy chat window 1240 to invite the selected screen names to theselected event. A message sent with the buddy chat window 1240 may beseen by all screen names for which the buddy chat window 1240 isdisplayed. The screen names for which the buddy chat window 1240 aredisplayed is listed in the screen name list 1244. More particularly, thebuddy chat window 1240 is displayed for each of AOLUser, randomcontact2,Mom, Dad, and Brother. The buddy chat window 1240 includes a messagehistory box 1242 in which an invitation to the event is displayed. Eachof AOLUser, randomcontact2, Mom, Dad, and Brother may process theinvitation in a manner similar to IM 1208. In particular, each ofrandomcontact2, Mom, Dad, and Brother may make changes to the event asdescribed above with respect to FIG. 12F. However, the proposed changesare received by all invitees to the event, as well as the invitor, withthe buddy chat window 1240. Therefore, all of the invitees and theinvitor are presented with the changes and may accept the changes ormake further changes to the event. When a buddy chat window 1240 isused, the modification process is more collaborative and the burden ofreceiving and accepting changes does not fall solely on the invitor,AOLUser.

FIGS. 13A-13F illustrate operations that may be experienced in oneimplementation of the above concepts. The operations include sharingelectronic content with multiple users.

Referring to FIG. 13A, while sharing electronic content, a user with ascreen name “AOL User” interacts with the buddy list interface 200. Theuser also may interact with an interface from which electronic contentto be shared may be selected, such as a file system interface 1300. Thebuddy list interface 200 and the file system interface 1300 may bedisplayed such that the user sees both the buddy list interface 200 andthe file system interface 1300 at the same time. The user may select thefile 1302 with the file system interface 1300 as the file to be shared.One or more screen names may be selected in the buddy list interface200. For example, in the buddy list interface 200, the screen names 204a (“randomcontact2”), 204 c (“Mom”), 204 d (“Dad”), 204 e (“Brother”),and 204 f (“Secretary”) have been selected. The Mom, Dad, and Brotherscreen names 204 c-204 e may be selected individually, or they may becollectively selected by selection of the Family group icon. Userscorresponding to the screen names 204 a and 204 c-204 e are online andavailable to receive instant messages, while a user corresponding to thescreen name 204 f is not online, as evidenced by location of the screenname 204 f within the “Offline” group.

Referring to FIG. 13B, the user may then drag the file 1302 towards thebuddy list interface 200, where the screen names 204 a and 204 c-204 fare selected, as indicated by an arrow 1304. Referring to FIG. 13C, thefile 1302 has been dragged from the file system interface 1300 over oneof the screen names 204 a and 204 c-204 f in the buddy list interface200, which have been previously selected as recipients of the file 1302.

Referring to FIG. 13D, separate IMs 1310 1312, 1314, and 1316 are shownfor each of randomcontact2, Mom, Dad, and Brother, respectively. An IMis not generated for Secretary because the user corresponding toSecretary is not available to receive instant messages, as evidenced bythe listing of Secretary in the Offline buddy group. Each of IMs 13101312, 1314, and 1316 includes an indication of the file 1302 that is tobe shared. The user may then send the instant messages 1310 1312, 1314,and 1316 to share the file 1302. In another implementation, the instantmessages 1310 1312, 1314, and 1316 may not be shown, and the instantmessages sharing the file 1302 with randomcontact2, Mom, Dad, andBrother may be sent automatically and transparently after the file 1302has been dropped on the screen names 204 a and 204 c-204 e. AOL Useralso may drag and drop the file 1302 into a buddy group name, such as,for example, “Family,” to share the file 1302 with those users includedin the corresponding buddy group.

Referring to FIG. 13E, a buddy chat window 1320 enables simultaneoussending of the selected file 1302 to the selected screen names that areonline. The user, AOLUser, may be given the option of using multipleinstant messages, as was done with respect to FIG. 13D, or a singlebuddy chat window 1320 to share the file 1302 with the selected screennames. A message sent with the buddy chat window 1320 may be seen by allscreen names for which the buddy chat window 1320 is displayed. Thescreen names for which the buddy chat window 1320 is displayed arelisted in the screen name list 1322. More particularly, the buddy chatwindow 1320 is displayed for each of AOLUser, randomcontact2, Mom, Dad,and Brother. The buddy chat window 1320 is not displayed for Secretary,because Secretary is not available to receive instant messages. Thebuddy chat window 1320 includes a message history box 1324 in which thefile 1302 is displayed to indicate that the file 1302 has been sent toall of the screen names in the screen name list 1322.

Referring to FIG. 13F, the user may select an alternate mechanism forsharing the file 1302 with the user corresponding to the screen name 204f with an interface 1330. The alternate mechanism is selected becausethe user corresponding to the screen name 204 f is not available toreceive the file in an instant message. The interface 1330 includes ane-mail button 1332 that enables the user to specify that the file 1302should be sent to Secretary in an e-mail message. The interface 1330also include an queue button 1334 that enables the user to send the fileto Secretary in an instant message that is queued for delivery the nexttime Secretary may receive instant messages. The interface 1330 alsoincludes a cancel button 1336 with which the user may indicate that thefile is no longer to be shared with Secretary.

In some implementations of the above concepts, presence informationdescribing the online or physical presence of users with whichelectronic content is to be shared may be used to determine how theelectronic content is delivered to the users. For example, each of theusers may have a cascaded delivery rule that may be resolved to identifyan appropriate delivery mechanism based on the presence of the user. Forexample, a delivery rule for a recipient of shared content may indicatethat when the recipient is online, instant messages should be used toshare electronic content with the recipient and that when the recipientis not online, e-mail should be used to share electronic content withthe recipient. More complicated rules may consider the physical locationof the recipient when identifying an appropriate delivery mechanism forthe recipient. In addition, the delivery rule may consider more than twodelivery mechanisms when identifying the delivery mechanism to be used.If a sender of the content does not have access to a delivery rule forthe recipient, then the recipient user may specify a delivery rule forthe recipient.

A number of implementations have been described. Nevertheless, it willbe understood that various modifications may be made without departingfrom the spirit and scope of the invention. For example, referring againto FIG. 1, each of the client systems 110 may be implemented using, forexample, a general-purpose computer capable of responding to andexecuting instructions in a defined manner, a personal computer, aspecial-purpose computer, a workstation, a server, a device, acomponent, or other equipment or some combination thereof capable ofresponding to and executing instructions. The client systems 110 mayreceive instructions from, for example, a software application, aprogram, a piece of code, a device, a computer, a computer system, or acombination thereof, which independently or collectively directoperations, as described herein. These instructions may take the form ofone or more communications programs that facilitate communicationsbetween the users of the client systems 110. For instance, suchcommunications programs may include e-mail programs, IM programs, filetransfer protocol (FTP) programs, and voice over internet protocol(VoIP) programs. The instructions may be embodied permanently ortemporarily in a machine, a component, a piece of equipment, a storagemedium, or a propagated signal that is capable of being delivered to theclient systems 110.

The client systems 110 include a communications interface (not shown)used by the communications programs to send communications through thenetwork 120. The communications may include, for example, e-mail, audiodata, video data, general binary data, or text data (e.g., encoded inAmerican Standard Code for Information Interchange (ASCII) format). Theclient systems 110 also include one or more input devices, such as akeyboard, mouse, stylus, or microphone, as well as one or more outputdevices, such as a monitor, touch screen, speakers, or a printer.

The network 120 typically includes a series of portals interconnectedthrough a coherent system. Examples of the network 120 include theInternet, Wide Area Networks (WANs), Local Area Networks (LANs), analogor digital wired and wireless telephone networks (e.g. a Public SwitchedTelephone Network (PSTN)), an Integrated Services Digital Network(ISDN), or a Digital Subscriber Line (xDSL)), or any other wired orwireless network. The network 120 may include multiple networks orsubnetworks, each of which may include, for example, a wired or wirelessdata pathway.

As with the client systems 110, the host server 130 may be implementedusing, for example, a general-purpose computer capable of responding toand executing instructions in a defined manner, a personal computer, aspecial-purpose computer, a workstation, a server, a device, acomponent, or other equipment or some combination thereof capable ofresponding to and executing instructions. The host server 130 mayreceive instructions from, for example, a software application, aprogram, a piece of code, a device, a computer, a computer system, or acombination thereof, which independently or collectively directoperations, as described herein. These instructions may take the form ofone or more communications programs. For instance, such communicationsprograms may include e-mail programs, IM programs, FTP programs, VoIPprograms, etc. The instructions may be embodied permanently ortemporarily in a machine, a component, a piece of equipment, a storagemedium, or a propagated signal that is capable of being delivered to thehost server 130.

Further, the host server 130 includes a communications interface (notshown) used by the communications programs to send communicationsthrough the network 120. The communications may include, for example,e-mail, audio data, video data, general binary data, or text data (e.g.,ASCII format).

Other implementations allow a user to create a calendar event withselected entities as invitees by a feature that is associated with, forexample, IM screen names. For example, a user may right-click on ascreen name to provide access to a “create event” feature that createsand opens a calendar event with the screen name inserted as an invitee.Further, multiple screen names may be selected using, for example,<shift> click or <control> click, and a right-click on the selected setmay provide access to a “create event” feature that creates and opens acalendar event with each of the selected screen names inserted asinvitees.

Throughout the description, a buddy list of an IM system is used toindicate a contact list that includes potential invitees to calendarevents. In various implementations, invitees to a calendar event areselected from the buddy list, and instant messages are used to sendinvitations to the calendar event to the invitees. However, othercontact lists may include potential invitees to calendar events, and theother contact lists may be used to send invitations to the invitees. Forexample, an e-mail address book may be used to select potentialinvitees, and e-mail messages may be used to send invitations to theinvitees. In addition, a list of participants within a chatroom/application may be used to select potential invitees, and chat maybe used to distribute the invitations. The potential invitees includedin the other contact lists may be organized into groups that may bemanipulated in a manner such as described above with respect to groupsof a buddy list.

The functional blocks, operations, and other disclosed features may becombined and performed in different orders and combinations, and may berepeated, omitted, and/or augmented with other features not explicitlydisclosed.

Various implementations perform, for example, one or more operations,functions, or features automatically. “Automatically” refers to beingperformed substantially without human intervention, that is, in asubstantially non-interactive manner. An example of an automatic processis a process that is started in response to a triggering event or inresponse to some action by a human operator which thereafter runs byitself.
